Description

In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]net/packet: fix a race in packet_set_ring() and packet_notifier()[EOL][EOL]When packet_set_ring() releases po->bind_lock, another thread can[EOL]run packet_notifier() and process an NETDEV_UP event.[EOL][EOL]This race and the fix are both similar to that of commit 15fe076edea7[EOL]("net/packet: fix a race in packet_bind() and packet_notifier()").[EOL][EOL]There too the packet_notifier NETDEV_UP event managed to run while a[EOL]po->bind_lock critical section had to be temporarily released. And[EOL]the fix was similarly to temporarily set po->num to zero to keep[EOL]the socket unhooked until the lock is retaken.[EOL][EOL]The po->bind_lock in packet_set_ring and packet_notifier precede the[EOL]introduction of git history.
